Special Issue Information
Dear Colleagues,
High-temperature composite materials are typical hard and brittle difficult-to-machine materials. The machining-induced stresses and temperature rise during processing can lead to structural warping, brittle fracture, edge chipping, and other surface defects, accompanied by severe tool wear, unstable machining quality, prolonged processing cycles, and low production efficiency. Therefore, developing machining methods for complex-shaped components that ensure high machining quality (dimensional and geometric accuracy plus surface integrity), high efficiency and low cost is of critical practical significance to meet the requirements of aerospace engines operating under high-temperature, long-service-life conditions.
Multi-energy field hybrid machining can effectively combine the advantages of different energy fields while overcoming the limitations of individual machining methods. This approach enables high-efficiency manufacturing of complex structures from difficult-to-machine materials with superior surface quality and geometric accuracy, representing a key breakthrough to address the bottlenecks of poor machining quality, low efficiency, and high costs.
By integrating low-energy ultrasonic vibration for cutting force modulation with high-energy electrical discharge for precise modification of the milling zone, the demanding requirements for high-efficiency, high-quality, and high-performance machining of high-strength, high-hardness, and heat-resistant composite materials can be satisfied.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Metals is an international peer-reviewed open access monthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
